Accelerating the energy transition of rural households in mountainous areas is an important step to improve energy poverty and mountain ecosystems and to help achieve carbon peaking and carbon neutrality. This paper explores the transformation of rural cooking energy in mountainous areas based on field investigation data from six villages in Chongqing. It systematically reveals the transformation process, driving factors and carbon emission changes in household cooking energy consumption in mountainous areas in the past 20 years by using mathematical statistics, multinomial logit models and the emission coefficient method. The results are as follows. (1) There has been a significant transition in the consumption of rural household cooking energy in mountainous areas. There has been a significant change in the proportion of different energy sources, including fuelwood (59.2%–1.9%), coal (16.5%–0%), gas (12.6%–15.5%), natural gas (6.8%–51.5%) and electricity (4.9%–31.1%). (2) The main driving factors of the household cooking energy transition in mountainous areas are income per capita, householder age, and householder education level. (3) The average annual household carbon emissions from rural household cooking energy decreased remarkably. The average annual household carbon emissions decreased from 6.80 t to 2.62 t in fuelwood (5.40–0.91 t), electricity (0.19–1.28 t) and natural gas (0.03–0.25 t) emissions during the study period. The contribution of this study is to investigate how the household cooking energy transition contributes to carbon peaking and carbon neutrality from a micro perspective. At the same time, this paper explores the mechanisms between the cooking energy transition and the ecological dividend of urbanization and proposes future reform initiatives for rural energy in mountainous areas to help achieve the goals of carbon peaking and carbon neutrality.

To secure effective and sustainable climate change policies, it is of the utmost importance to create synergies between socioeconomic and environmental development goals. Payments for Ecosystem Services (PES) programs are being promoted as a suitable mechanism furthering, among others, carbon offsetting and poverty reduction in ecologically fragile areas of developing countries. Rural households are compensated for the loss of property and business income through income transfers and potential job opportunities connected to environmental programs. While the potential pro-poor effects of such policies are well recognized, the impact of PES on extremely poor households has not been systematically reviewed. Drawing on a pooled cross-sectional dataset of 5225 households in the Province of Sichuan, this paper analyzes the income and distributional effects among poor households in rural China participating in a forest carbon sink (FCS) program. To be able to make causal inferences, we employ an Instrumental Variable (IV) approach to control for potential endogeneity and self-selection. Our results indicate a strong need to adjust the PES program: While moderately poor rural households benefit from program participation, extremely poor rural households, in fact, suffer net losses. The main reason is that income reduction resulting from limited access to forest resources is compensated mainly via wage income from participating in forest tending work. Extremely poor households with low labor ability cannot make use of these job opportunities, and thus they'll not only fail to benefit but even incur losses from a PES program. While PES programs can be a viable tool for poverty reduction in underdeveloped regions due to their overall pro-poorness, they need to be accompanied by additional benefits for extremely poor rural households to avoid net losses among marginalized population groups especially.
